scrub system. The brush deck is fixed and integrated in the machine with a support bracket. The adjusting sys-
tems adjusts the forward speed, while the handwheel on the deck adjusts the machine straight-forward drive
The brush working pressure is functional to the machine designed balance
The brush motor (M1) is supplied by vacuum brush motor relay (K1) which is driven by the program selection
knob/rotary switch (SW1) when it is turned to 1, 2 or 3, and the machine start-up enabling push-button (SW2)
is pressed The circuit is protected by the brush motor fuse (F1)
